PLEASE HELP ASAP!! A 3.81-gram sample of NaHCO3 was completely decomposed in an experiment. 2NaHCO3 → Na2CO3 + H2CO3

In this experiment, carbon dioxide and water vapors combine to form H2CO3. After decomposition, the Na2CO3 had a mass of 2.86 grams.

A. Determine the mass of the H2CO3 produced.

B. Calculate the percentage yield of H2CO3 for the reaction.

Show your work or describe the calculation process in detail.

A. the mass is 1.41g

B. the percentage yield is 84.44%

Explanation:

The decomposing reaction is  2NaHCO3 → Na2CO3 + H2CO3  so, 2 moles bicarbonate decompose to 1 mol of carbonate and 1 mol of carbonic acid. Then convert the mass to moles, 3.81g / 1 mol / 84g = 0.0454 moles

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
